Authorities in Austin, Texas continue to hunt for those responsible for a series of package bombs after the city was hit on Sunday by a new explosion.
Two men in their 20s were rushed to a hospital after emergency services responded to reports of a bomb explosion in the west of the capital just after 8:30 p.m. CT.
Police told a press conference that the wounded men were taken to a hospital, but their injuries were not life-threatening.
They added that the explosion may have been detonated by a trip wire.
"We have a scene where it is obvious an explosion has taken place," Austin Police Chief Brian Manley said. "We just simply do not know a lot at this point."
"Given that there may have been a different triggering mechanism in this device, we wanted to get that out as early as possible," Manley later added.
He also told people to stay in their homes and avoid touching any suspicious packages, but did not say whether there was any link between the latest blast and the earlier parcel bombs.
The FBI said on Twitter that its agents were at the scene of Sunday's explosion in a residential neighborhood on the west side of the city, several miles from the east side neighborhoods where the earlier blasts occurred.
